As of 10 April 2026, asteroid 2024 YR4 is under routine monitoring by professional and amateur observers. Continued optical (and where available radar) measurements have refined its orbit, and current trajectories show no predicted impact with Earth in the coming decades.
Size estimates place 2024 YR4 in the small-asteroid category (roughly tens to a few hundred meters across); ongoing observations aim to improve estimates of its size, shape and spin. Agencies such as NASA’s Center for Near-Earth Object Studies and the ESA NEO Coordination Centre post updated orbit and risk information as new data arrive.
